One Line Wonder

Draw every path exactly once

One Line Wonder is a relaxing puzzle game built around a simple challenge: trace every path in the puzzle exactly once without retracing any edge.

Each level presents a network of connected points. Choose where to begin, plan your route, and draw one continuous line through the entire shape. The idea is easy to understand, but increasingly complex layouts and additional rules demand careful thinking.
